Description
Technical field
It is true more specifically to a kind of nuclear power station hydraulic damper the present invention relates to hydraulic damper
Empty injection system and method.
Background technology
Hydraulic damper for nuclear power station is a kind of speed or the sensitive antivibration branch of acceleration response to be taken up
Put, for protecting the key equipment or pipeline that are supported by.
Damper does not work to the slow motion that the normal thermal expansion of equipment or pipeline causes.It is being subjected to
During sudden applied load (earthquake or pressure jump), damper reforms into one and is rigidly connected and carrys out limiting displacement,
The purpose of antivibration supporting is reached with this.
The nuclear power damper full set technology of the sum of applicant company nineteen ninety-five Introduced from Japan three, is introducing
On the basis of technology, focus on improving the innovation ability of itself, in hydraulic pressure, mechanical damping
Device key technology and core link are furtherd investigate, and realize very big breakthrough, and exploitation is ground on this basis
Core level hydraulic pressure, mechanical damper series of products are made, and has been used in Qinshan first stage of the project.Take the lead in realizing
The production domesticization of core level damper, has filled up domestic blank.
As damper designs for many years are manufactured, damper production domesticization, optimization, standardization, technique energy
Power, mounting technology progress, greatly reduce cost.
At present, traditional filling oil mode for it is artificial fill oil, it is necessary to assembly crewman tension and compression piston rod will repeatedly
Removal of bubbles in hydraulic damper, process is cumbersome time-consuming, and a general damper needs several hours
Oiling even could be completed within several days to be tested, operating efficiency is very low, when produced in large volumes,
It is clearly felt that inefficient, influence progress；Meanwhile, also exist hydraulic damper oiling it is insufficient or
There is bubble in oil, the dynamic and static state performance for causing damper is reduced, the poor fluidity of fluid, and is damped
There is more small-sized fit clearance and damping structure inside device, it is internal after oiling to there may be
Space or bubble, can influence the compressible coefficient of fluid, and then to the dynamic and static state performance product of damper
Raw adverse effect.It is fast more many than artificial in speed and vacuum fills oil and fills oil using oil pump, particularly get over
The damper influence of the damper and volume production of large-tonnage is bigger.
The content of the invention
For disadvantages mentioned above present in prior art, it is an object of the invention to provide a kind of nuclear power station liquid
Pressure damper vacuum oil system and method, can be automatically performed by the present invention damper is vacuumized,
The hydraulic damper vacuum oil of the work such as oiling and exhaust, improves oiling efficiency and preferably solves
There is dead angle when filling in damper of having determined.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of nuclear power station hydraulic damper vacuum oil system, including damper and located at damper top
Pouring orifice and exhaust outlet, also including fuel tank, oil conservator, vavuum pump and several seal tubes, oil storage
Device top is provided with the first valve and the second valve, and described pouring orifice connects fuel tank by seal tube,
Described exhaust outlet connects the first valve of oil conservator by seal tube, and the second valve of oil conservator leads to
Cross seal tube connection vavuum pump.
Described tank bottoms are provided with the 3rd valve, and by seal tube connection damper pouring orifice.
Described oil conservator bottom is provided with draining valve.
A kind of nuclear power station hydraulic damper vacuum oil method, comprises the following steps：
S1, the draining valve of nuclear power station hydraulic damper vacuum oil system is closed；
S2, by the 3rd valve closing, then the first and second valves is opened；
S3, opens vavuum pump, by the evacuating air in damper and oil conservator；
S4, is then shut off the second valve, opens the 3rd valve, make hydraulic oil in fuel tank because pressure difference from
It is dynamic to enter into damper；
S5, hydraulic oil is introduced into damper bottom, and gradually rises, until damper exhaust outlet has oil
Outflow, then it represents that the hydraulic oil in damper is already filled with.
In described S5, if hydraulic oil can not be filled once, need to repeat S1 to S5 steps.
In summary technical scheme, it is an advantage of the current invention that can be automatically performed to damper
Vacuumize, the work such as oiling and exhaust, only need the shorter time just to complete an oiling for damper
Operation, can realize that the device of a people one completes all of oiling task, substantially increase operating efficiency.
Brief description of the drawings
Fig. 1 is integrally-built schematic diagram of the invention；
Fig. 2 is the flow chart of the inventive method.
Specific embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 1, a kind of nuclear power station hydraulic damper vacuum oil system provided by the present invention
System, it is same as the prior art, equally also include damper 3 and the note located at the top of damper 3
Hydraulic fluid port 2 and exhaust outlet 4, are not repeating herein.Unlike the prior art, present invention additionally comprises
Fuel tank 1, oil conservator 6, vavuum pump 8 and several seal tubes 10, the top of oil conservator 6 are provided with first
The valve 7 of valve 5 and second, the bottom of fuel tank 1 is provided with the 3rd valve 11, and is connected by seal tube
The pouring orifice 2 of damper 3, described pouring orifice 2 connects fuel tank 1 by seal tube 10, described
Exhaust outlet 4 connects the first valve 5 of oil conservator 6 by seal tube 10, and the bottom of oil conservator 6 is provided with
Draining valve 9, the second valve 7 of oil conservator 6 connects vavuum pump 8 by seal tube 10.
Incorporated by reference to shown in Fig. 2, before the oiling of damper 3 work is carried out, first by nuclear power station hydraulic damping
The draining valve 9 of device vacuum oil system need to be closed, and the 3rd valve 11 is closed, first,
Second valve 5,7 is opened, and is opened vavuum pump 8 and is extracted the air in damper 3 and oil conservator 6 out,
Damper 3 and oil conservator 6 is in vacuum state (depending on size of the vacuum according to damper tonnage).
Be then shut off the second valve 7, open the 3rd valve 11 so that hydraulic oil in fuel tank 1 because pressure difference from
Dynamic to enter into damper 3, due to the relation of gravity, hydraulic oil is into first flowing into after damper 3
Up to the bottom of damper 3, and gradually rise, remaining air in damper 3 progressively all discharged,
If hydraulic oil can not once fill damper 3, repeat the above steps, until damper 3 is vented
Mouth 4 has hydraulic oil liquid to flow out, then it represents that fluid has been filled in damper 3.When the inner fluid of damper 3
When filling, the hydraulic oil of unnecessary spilling is flowed into oil conservator 6 by exhaust outlet 4, in oil conservator 6
The hydraulic oil being recovered to can be reused.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to
